 * translations on GFXv9 and later AMD GPUs can return XNACK and retry
 * the access until a valid PTE is available. This is used to implement

 *
 * On output, @xnack_enabled returns the (new) current mode (0 or

 *
 * The XNACK mode fundamentally changes the way SVM managed memory works
 * in the driver, with subtle effects on application performance and

 *
 * Enabling XNACK mode requires shader programs to be compiled
 * differently. Furthermore, not all GPUs support changing the mode
 * per-process. Therefore changing the mode is only allowed while no
 * user mode queues exist in the process. This ensure that no shader
 * code is running that may be compiled for the wrong mode. And GPUs

 * mode from occurring. All GPUs used by the process must be in the
 * same XNACK mode.

 * Therefore those GPUs are not considered for the XNACK mode switch.
